scipy.interpolate imports --> lapack errors

Hey y'all,
When I try to import items from scipy.interpolate, I get the following error:
Traceback (most recent call last):
File "plot.py", line 4, in <module>
from scipy.interpolate import bisplrep, bisplev
File "/usr/lib/python2.6/site-packages/scipy/interpolate/__init__.py",

from basic import *

from lapack import get_lapack_funcs
File "/usr/lib/python2.6/site-packages/scipy/linalg/lapack.py", line
18, in <module>
from scipy.linalg import clapack
ImportError: /usr/lib/python2.6/site-packages/scipy/linalg/clapack.so:
undefined symbol: clapack_sgesv
As far as I know, I have lapack, blas and atlas all installed, so I'm
pretty perplexed. Any ideas?
Thanks,
